Technical Perspective: The Compression Power of the BWT
"Resolution of the Burrows-Wheeler Transform Conjecture," by Dominik Kempa and Tomasz Kociumaka, finally settles the question of how well r in the BWT captures repetitiveness.

Resolution of the Burrows-Wheeler Transform Conjecture
In this paper, we show that r = 
(z log2 n) holds for every text. This result has numerous implications for text indexing and data compression.
